Taste wise, annoyingly have to vote for muscletech's nitrotech i used to drink when first started half a decade ago (stupid times wasting a lot of money on supplements)

Grenade's hydra 6 chocolate tasted damn good with unsweetened peanut better blended.

For your case, probably try add in banana, pb or chocolate milk to dilute the soy taste? Or just be a man and gulp it down 1 shot. Lol

Honestly speaking, i cannot really differentiate these stuffs, apart from it tastes good, or just bad (nutrex's muscle infusion came to mind).
